Seachem Pond Flourish Iron 500ml

Pond Flourish Iron is the companion product to Pond Flourish and Pond Flourish Tabs. It is a complexed ferrous iron product that contains 10,000 mg/L of iron and is ideal for iron maintenance in the natural pond.Plants are able to much more easily derive a benefit from Flourish Iron than from EDTA-iron sources because all EDTA iron is in the ferric (Fe+3) state. Since plants require iron in the ferrous (Fe+2) state, additional physiological energy must be expended in order to extract the ferric iron from EDTA-iron and then convert it to the ferrous form.

Directions: Use 1 tablespoon per 100 gallons once or twice a week as required to maintain about 0.1 mg/L iron. Use MultiTest: Iron test kit to monitor iron concentrations. Use only in a contained pond as directed. This product is not intended for natural bodies of water or agricultural use.
